SPINNING-MACHINE.

Specification of Letters Patent. Patented July 13,1915.

Application filed February 24, 1912., Serial No. 679,722.

To all whom it may concern Be it known that I, ED'WARD J. COTTE citizen of the United States, residing at Philadelphia, Manayunk Station, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Spinning-Machines, of, which the following is a specification.

This invention relates to spinning machines and more particularly to a machine especially designed for twisting cotton, wool and other materials.

The primary object of the invention is to provide a machine of simple and durable construction, which shall take the yarn directly from a carding machine or from a suitable yarn carrying roller and spin or twist the same into thread, twine or cord and simultaneously wind the material on a cop or bobbin, thus dispensing with the usual mule and reel mechanism employed for this purpose and consequently materially reducing thecost of manufacture.

A further object is to provide a machine which twists and winds the materials con tinuously, the amount of twist imparted to the yarn being governed by the speed of the feed rollers.

A further object is to provide IIlQflllS fOl reciprocating the bobbin carrying spindle during the operation of the machine, whereby the yarn may be uniformly distributed on the cop or bobbin.

A further object isto provide means forpermitting the removal of a filled cop or bobbin from the flier and the replacement of an empty bobbin without the necessity of shutting down the machine or otherwise in-,

terfering with the operation thereof.

A further object is to provide the flier with a spring eye or loop which serves toguide the yarn on the cop or bobbin during the reciprocation of the spindle and also serves to prevent breakage of the yarn, should the feed of the latter to the bobbin be interrupted-or otherwise retarded during the winding operation.

A still further object is to provide a spinning machine, the construction of which isunderstood that various changes in form, proportions and minor details of construction may be resorted to within the scope of the appended claims.

For a fuller understanding of the. invention and the merits thereof, reference is to be had to the following description and accompanying drawings, in which I Figure 1 is a perspective view of a spin ning machine constructed in accordance with the present invention,- a group. or gang of fliers being shown arranged" on opposite. sides of a main frame and receiving yarn from an overhead roller; Fig. 2 is an end view; Fig. 3 is an enlarged vertical sectional view partly in elevation of one of the fliers and its associated parts; F ig.. i is an enlarged detail sectional'view taken on the line 1-4: of Fig. 3 and looking in the direction of the arrow; Fig. 5 is a vertical sectional view of the upper portion of the machine, showing the arrangement of the feed rollers; Fig. 6 is a perspective view of the mechanism employed for reciprocating thebobbin carrying spindle to effect the uniform distribution of the yarn on the bobbin; Fig. 7 is a detail perspective view. of one of the spindles detached, showing a spool or bobbin in position thereon.

Corresponding and like parts are referre to in 'the following description and indicated in all the views of the drawings by the same reference, characters.

The improved spinning machine forming the subjectmatter of the present invention comprises a main supporting frame including spaced end pieces 5 having their side walls inclined upwardly and unitedby lon-.

gitudinal connecting bars 6,. Secured to the is preferably wound on the spool or roller 9 in sections one end or strand of the yarn of each section being extended downwardly to a. flier indicated at- 10. The fliers lOarepreferably arranged in staggered relation on opposite sides of the spinning frame and as these fliers are similar in constr-uctionand operation, a detailed description of one will suffice. I i

Each flier-comprises spaced arms or supports 11 having laterally extending flanges 12 whichbear against the adjacent longitu dinal bars 6 of the spinning frame and to which they are rigidly secured by bolts or similar fastening devices 12. The flier 10 is mounted for rotation between the supports 11 and is provided with oppositely disposed hollow trunnions 13 one of which serves to receive the adjacent strand of yarn from the roller 9. The end pieces 14 of the frame are connected by longitudinal bars 15 to which is rigidly secured a transverse bar 16 having a center bearing 17 in which is loosely mounted one end of a bobbin carrying spindle 18 and which may be provided with anti-friction devices to promote the free relative movement of the spinning frame and the spindle.

Detachably secured to the spindle 18 is a spool or bobbin 19 on one end of which is pivotally mounted at 20 a spring locking member or catch 21 adapted to enter a notch 22 formed in the spindle so as to key the spool or bobbin on the spindle and thus cause the two to move in unison. The catch 21 is provided with a suitable finger piece 23 to facilitate releasing the catch from a stud 24 on the spool, which stud by engagement With the catch serves to assist in preventing accidental displacement of said spool during the winding or twisting operation.

Secured to one of the side bars 15 of the flier, is a spring arm 25 having a terminal eye 26'through which the yarn passes to the bobbin 19, there being a rigid or stationary eye or guide 26 on the side bar of the spinning frame near the upper end thereof to hold the yarn away from the upper end flange of the bobbin and thereby prevent said flange from cutting or breaking the yarn. As will be readily understood on reference to the dotted lines, if the yarn passed directly from the hollow trunnion 13 to the eye 26, it would fall against the edge of the flange of the bobbin and would thereby be cut and broken.

The lower trunnion 13 of the flier is projected downwardly through the bearing in the adjacent support 11 to form an extension 27 to which is keyed or otherwise rigidly secured a wheel or pulley 28. Extending over the wheel or pulley 28 is a belt 29 which also encircles a relatively large pulley 30 mounted ona power shaft 31. The power shaft 31 is journaled in suitable bearings 32 on the spinning frame and extends longitudinally of said frame and between the side walls thereof as best shown in Fig. 1 of the drawings. Secured to the shaft 31, is a relatively small pulley 33 over which extends a belt 34 leading to an engine or other suitable motor 35 so that when the motor is operated,

'motion will be transmitted through the medium of the belts 34 and 29 to the wheel 28 and thus rotate the flier.

Secured to one of the supportsll, is an arm 36 having an opening therein to permit power the passage of the spindle 18, said arm being provided with a laterally extending flange 37 to which is rigidly secured one end of a spring 38, the other end of said spring being provided with a friction block 39 having a bearing 40 therein to permit the passage of the adjacent end of the spindle 18. Extending laterally from the arm 36 at a point opposite the bearing block 39, is a lug 41, the inner face of which is cut-away to form a substantially semi-circular socket for the reception of a removable plug 42, preferably formed of Babbitt metal, there being an adjusting screw 43 extending through the lug 41 and engaging the plug 42 so that the latter may be moved into and out of engagement with the spindle at will. An adjusting screw 44 is also preferably threaded in the flange 37 for engagement with the spring 38 to permit the tension of said spring to be adjusted when desired. Thus it will be seen that the plug 42 in conjunction with the block 39 serves to center the spindle 18 in the flier and prevent wabbling movement thereof during the twisting operation. It is to be understood, however, that the members 39 and 42 do not bear on the spindle with sufficient force to interfere with the free movement of the spindle within the flier, as this spindle must be free to reciprocate within the flier in order to effect a uniform distribution of the yarn on the spool or bobbin, as will be more fully explained hereinafter.

Pivotally mounted on the main supporting frame at 45, are spaced arms 46 having their outer ends bifurcated at 47 to receive the terminal trunnions 48 of a horizontally disposed supporting bar 49, one of said bars being arranged on each side of the main supporting frame, as shown. Each supporting bar is provided with a series of openings 50 adapted to receive the lower ends of the spindles 18. Pivotally mounted at 51 on the lower faces of the bars 49, are plates 52 ha\ ing depressions formed therein which constitute bearings 53 for the cone-shaped ends of the spindles 18. By swinging the plates 52 laterally on their pivotal axes, the spindles 18 may be lowered through the openings 50 so as to cause the upper ends of said spindles to clear the bearings 17 on the fliers and in which position, the filled spools or bobbins 19 may be readily detached from the spindles and replaced by empty spools without interrupting or otherwise interferring with the operation of the machine. The arms 46 on each side of the machine are connected by a rod 54 to which are secured spaced pitmen or levers 55, the upper ends of which are provided with slots 56 to permit the passage of an actuating shaft 57. Keyed or otherwise rigidly secured to each shaft 57, are heart-shaped cams 58, which serve to push up on or return the spindles 18 to elevated position after said spindles have been lowered or depressed by the weight of the bobbins thereon. Thus it Will be seen that as the fliers revolve, the weight of the spools or bobbins carried by the spindles 18 will depress the horizontal bars 19 and permit the spindles to drop while the cams 58 will return the spindles to elevated position, thereby continuously reciprocating said spindles and causing the yarn to be uniformly-wound or distributed upon the spools during the operation of the machine. The levers 55 are provided with suitable rollers 59 which operate within the cams 58 to effect the raising and lowering of said levers. If desired, however, any other suitable mechanism may be employed for effecting the reciprocation of the spindles within the fliers.

One end of each shaft 57 is provided with a cone-shaped roller 60 which co-acts with a similar roller 61 journaled in a suitable casing 62, the last-mentioned roller being provided with a sprocket wheel 63 which receives a sprocket chain 64 extending to a sprocket wheel 65 on the main driving shaft 31. Projecting through a slot in the casing 62, is a shipper lever 66, the inner end of which is bifurcated for engagement with a belt 67 so that by shifting the belt 67 longitudinally of the rollers 60 and 61,. the shaft 57 may be caused to rotate either fast or slow and consequently govern the reciprocation of the bobbin carrying spindles within the fliers.

Mounted for rotation directly beneath the yarn carrying spool 9, is a feed roller 68, one end of the shaft of which is projected longitudinally beyond the adjacent end of the main supporting frame and is provided with a sprocket wheel 69 over which extends a sprocket chain 70 leading to a similarsprocket wheel 71 mounted on the shaft 72 of a lower feed roller 73. Secured to the shaft 72 of the lower feed roller, is a coneshaped roller 74 which co-acts with a similar cone shaped roller 75 mounted on a stub shaft 76. Inter-posed between the rollers 7 1 and 75, is a belt 77 which may beadjusted longitudinally of said rollers by means of a lever 78 so as to change the speed of rotation of the upper and lower feed rollers 68 and 73 and thus retard or accelerate the passage of yarn from the spool 9 to the fliers. Journaled between the uprights 7 and preferably arranged at one side of the lower feed roller 73, is a guard roller 79 having a series of recesses 80 formed therein for the reception of suitable lift or weighted rollers 81, which latter rest loosely on the lower feed roller 73 and serve to retain the strands of yarn in contact therewith. It will be understood that the feed rollers 68 and 73 rotate in unison to prevent bulging or breaking of the yarn, but that the speed of both rollers may be simultaneously changed or varied by shifting the belt 77 so as to retard or accelerate the passage of the yarn to the fliers.

Secured to the power shaft 31, is a pulley 82 over which extends a belt 83 leading to a relatively small pulley 84 on the stub shaft ever, the yarn may be fed directly from a carding machine instead of from the roller9.

In operation, the strands of yarn are passed downwardly between the lower feed roller 73 and the lift rollers 81 and overthe guard roller 79 and thence through the up-. per hollow trunnions of the adjacentfiiers and through the eyes 26 and 26 to the bob-- As the flier revolves, a reciprocatory bin. motion will be imparted to the spindles 18 through the medium of the heart-shaped cams 58 so that the yarn will be twistedand uniformly wound on the spools or bobbins.

It will here be noted that the fliers revolve at a greater rate of speed than the feed rollers'so that the passage of the yarn to the fliers is slightly retarded and the twisting of the yarn effected before the yarn is wound on the spools or bobbins. It will also be noted that by increasing or decreasing the speed of the feed rollers 68 and 73, the amount of twist imparted to the, yarn may be controlled at will. For example, by increasing the speed of the feed rollers, the amount of twist imparted to the yarn may be lessened and the winding of the yarn on the spools or bobbins accelerated, While by decreasing the speed of the feed rollers, the passage of the yarn ,to the bobbins will be retarded so that the twist of the yarnwill be increased and the rapidity of the winding of the yarn'on the bobbin correspondingly decreased; in other words, the amount of twist imparted to the yarn is under the control of the yarn feeding mechanism and is governed by the acceleration or retardation of said yarn feeding mechanism which may be accomplished without stopping the machine.

The spring 25 is a guide for the yarn and is arranged midway the limits of the reciprocatory movement of the bobbin so that the yarn will be wound evenly thereon. The eye 26 of the spring remains at a fixed distance from the spindle under normal position, but should the yarn contain some hard substance, such, for example, as a grain of sawdust, the spring will yield and move toward the bobbin thereby avoiding a break in the yarn. The obstruction, when it reaches the feed rollers, causes a momentary jar or stoppage of the rolls and creates an abnormal strain between the rolls and the bin recovers from the jar.

It will be noted that the bobbin is not rotated except by its connection with the spinning frame through the yarn and, consequently, the pull on the yarn is the same throughout the spinning operation. As the yarn is wound on the bobbin and the weight of the same increases, the yarn is fed to the bobbin through a greater radius and consequently exerts a greater leverage to overcome the inertia of the bobbin and maintain constant the relative speeds of the bobbin and the frame. As the spindle is loosely mounted in the flier, it is obvious that when yarn is fed freely through the feed rollers, the flier will revolve much faster than the spindle and consequently wind the yarn on the bobbin, and that when the speed of the feed rollers is decreased, the passage of the yarn to the flier will. be retarded and cause the spindle to revolve with the flier, and as the speed of the flier is greater than the speed of the feed rollers the yarn will be twisted before being wound upon the bobbin. In other words, when the feed rollers are speeded, the twist is light and, conversely, when the rotation of the feed rollers is retarded, the amount of twist imparted to the yarn will be correspondingly increased. By crossing the strands of the belt 29 either a right or a left hand twist may be imparted to the yarn.

the block 4-2 on the spindle may be regulated so as to permit the twisting of hardspun yarn or twine.

The main supporting frame is preferably formed in sections so that a series of such 7 Also, by adjusting the screws L3 and 44, the friction exertedby sections may be coupled up and the fliers thereon actuated from a common power shaft. One frame only is shown in the drawings however.

It will of course be understood that as many fliers may be arranged on each sec tion of the main supporting frame as may be found desirable in practical operation, and that any suitable mechanism may be employed for changing the speed of the feed rollers and for reciprocating the bobbin carrying spindles.

From the foregoing description it will be seen that there is provided a machine, the construction of which is such that vibration is reduced to a minimum, the efliciency or out put thereof materially increased, and the cost of manufacture correspondingly decreased. i

Having thus described the invention, what is claimed as new is: 1
